Default 2003 S430 Battery Draining : Possible Rx

Im NO mechanic, but YouTube has saved me lots of $$$s.
I am testing this fix now.
alternator and battery are both good.
After 2 days battery was dead again, so I now charge it at nite until I find the real drain.. Per this video I have removed the passenger fuse..
will buy a Multimeter to check voltage pull today and will report back.



Other possible fixes:
Parasitic Draw Test
